Symbols for plastics and rubber materials -- Schedule for symbols for compounding ingredients
This Part of BS 3502 is intended to provide unambiguous symbols for compounding ingredients used in plastics and rubbers.
The types of ingredients covered are:
The schedule includes, in general, only those symbols that have come into established use, and its aim is both to prevent the occurrence of more than one symbol for a given ingredient and, as far as is practicable, to prevent the interpretation of more than one meaning for a given symbol.
The symbols are primarily intended to be a convenient short-hand for chemical names in publications and other written matter. They are also suitable for data storage systems.
NOTE The list does not purport to be comprehensive, and symbols for other compounding ingredients will be added in future revisions.
Provides unambiguous symbols comprising accelerators and vulcanizing agents, activators and process aids, antioxidants and antiozonants, blowing agents, plasticizers, retarders of vulcanization, and fillers and reinforcing materials for plastics.
